Would it be worth introducing an interface so we could return a "no-op" implementation when the real implementation can't be loaded? That would avoid all these null-checks... some of which will be checked on every profiled exception.

Yes, I've been thinking that we should use SPI approaches more often.
I'd really like code to request an implementation of an interface -- and when one isn't available get back a Null/NoOp version in instead.

I extracted an interface. done in d2460a2
